  • Applications

    Phenylacetaldehyde diethyl acetal (CAS 6314-97-2) is primarily used as an aldehyde-protecting group in multi-step organic syntheses, enabling temporary masking of the reactive aldehyde functionality. It is also employed as a fragrance-related intermediate and odorant surrogate in perfumery, contributing a floral note while offering greater formulation stability. The compound serves as a synthetic building block for aroma chemicals and other specialty chemicals, and can function as a processing aid or intermediate in coatings, inks, and adhesives. In polymer and plastics contexts, it may act as a precursor for functionalized monomers or as a controlled-release fragrance component in polymer matrices. It may also be evaluated for use in cosmetic or personal care formulations as an aroma ingredient, subject to local regulations and formulation limits.
